Concrete Countertop Solutions RT-001 Straight Z Poolform Receiver Track. The Z Poolform Receiver Track is used to mount the Poolform on top of the pool wall of a concrete or fiberglass pool. This is not necessary for a vinyl liner pool because the Poolform will plug into the liner track. The Receiver Track can be fastened to the pool wall either with the use of our 1" Construction Screws or our 2" Polyester Mounting Tape.
